Lipid 4.2 is serious for people with cardiovascular disease or hypertension or diabetes and requires active medication, while it is slightly less serious for people without underlying disease, but also requires active medical attention. Lipid management includes triglycerides and LDL cholesterol. The appropriate level of LDL cholesterol is <3.4mmolL. For people who already have hypertension, diabetes, coronary heart disease, cerebral infarction, etc., the target of LDL level control is more stringent, and it needs to be controlled to <2.6mmol/L or even <1.8mmol/L in order to slow down the progress of the disease or related complications. The majority of the population can only be controlled by medication. The normal range of appropriate triglyceride levels is <1.7mmol/L. When triglyceride levels are 4.2mmol/l, the risk of pancreatitis and cardiovascular disease increases, and active medication is needed to lower triglycerides. For people who do not have underlying diseases, abnormal blood lipid levels also require a reasonable diet, appropriate exercise and weight control under the guidance of a doctor to reduce blood lipid levels. When the blood lipid level is 4.2, it is necessary to actively consult a doctor to determine the severity of the problem according to individual circumstances, and follow the doctor's instructions to carry out standardized treatment.
